text: Grunenberg and N. Goldberg probed the bond strength of a Ga-Ga triple bond by calculating the compliance constants of digallium complexes with a single bond, a double bond, or a triple bond. The results show that the Ga-Ga triple bond of a model Na[H-GaGa-H] compound in C symmetry has a compliance constant value of 0.870 aJ/Å is in fact weaker than a Ga-Ga double bond (1.201 aJ/Å).
